Template:InfoboxCharacter Black Lady is an evil grown-up version of Chibiusa Tsukino. She was corrupted by Wiseman (Death Phantom) in the Sailor Moon R season. In the English dub, her name is changed to Wicked Lady.
In the anime, the Wiseman tells Chibiusa that no one on Earth likes or believe in her, and in the future, the people on this planet thinks that they know she was a villain that caused the destruction of Crystal Tokyo. Because of this, Chibiusa became the perfect candidate to absorb the Dark Crystal, and turn into the Black Lady.
Her friend, Luna-P, is also transformed into an evil minion too. When Black Lady touches it while embracing it, the moon crescent on its forehead turns to that of the Black Moon Clan; not only that, but the Dark Crystal's power is very contagious, to humans, and even machinery, when touched, and Black Lady uses the new Black Luna-P to fight the Sailor Senshi.
ChibiUsa goes to the Door of Space-Time after remembering how everyone in Crystal Tokyo teased her and how she met Sailor Pluto. But seeing Pluto so happy, she thinks that no one really needs her in Crystal Tokyo anymore. So, as she tries to get back to the 21st century, she, unnoticing this, then drops her key near the Door of Space-Time.
Since you can't get in any time period from the Door of Space-Time without the Space-Time Key, this shows you only a warp to be never seen or heard from again if you are warped in this hole. This is when ChibiUsa realizes that she left her key behind. Wiseman then appears and pretends to be her ally, and comforts her by saying that he needs her. Wiseman then takes ChibiUsa's hand, and a major space-time storm occurs after ChibiUsa takes his hand. Pluto knows that this was caused by ChibiUsa being in a major transformation.
Later in the next act or so, an adult-like woman who strongly resembles ChibiUsa appears next to Wiseman as a shadow. She then introduces herself as Black Lady at the beginning of an act titled "Attack, Black Lady". She is often seen giggling evilly. She discards Luna-P, regarding it as a foolish toy. She attacks with black power and also hynotizes Tuxedo Mask to be on her side.
How She Revives Back to ChibiUsa
After a long and hard fight, Sailor Moon and Tuxedo Mask convince Black Lady that she is loved and that she has misunderstood her parents' actions. Black Lady is then turned back into Chibiusa and Luna-P is too; their crescents return to normal. Chibiusa then joins Sailor Moon to kill the Death Phantom.
In the manga, Sailor Pluto helps Sailor Moon stops Dimande from merging the two crystals together with her Time Stop attack. Unfortunately in doing so, she dies and believes she had failed to protect Chibusa from the Black Moon Clan. Black Lady snaps out of it and mourns for her friend's death. This triggers her transformation into Sailor Chibi Moon.
